Description

【発明の詳細な説明】 複合プラスチック・バイブ １地豆１ 本発明は複合プラスチック・バイブに関する。[Detailed description of the invention] Composite plastic vibrator 1 local beans 1 FIELD OF THE INVENTION The present invention relates to composite plastic vibes.

通常のプラスチック・バイブ、一般的には塩化ビニール、ポリプロピレン、高密 度ポリエチレン、などの熱可塑性材料による押出プラスチック・バイブが、水密 性を有するのみならず化学的に腐食性の製品に対する耐性があるので、液体の搬 送に極めて適している事は知られている。Ordinary plastic vibes, typically vinyl chloride, polypropylene, high density Extruded plastic vibes made from thermoplastic materials, such as polyethylene, are watertight. It is chemically resistant to corrosive products, making it ideal for transporting liquids. It is known that it is extremely suitable for transportation.

１１且ｌ しかしながら、このような公知のバイブの欠点は、極めて高い圧力に対する充分 な抵抗力が無いので、高圧下における液体の搬送には使用出来ないことにある。11 and l However, the disadvantage of such known vibrators is that they do not have sufficient resistance to extremely high pressures. Because it has no resistance, it cannot be used to transport liquids under high pressure.

モして又、プラスチック・バイブ、一般には熱可塑性の、しかし好ましくはポリ エステル、ビニール・エステル、エポキシ、などの熱硬化性の材料によるプルト ルージョン・プラスチック・バイブが圧力に耐えるような目的には極めて適して いることも、知られている。Also, plastic vibrators, generally thermoplastic, but preferably poly Pluto with thermosetting materials such as ester, vinyl ester, epoxy, etc. Lusion plastic vibrators are extremely suitable for pressure-bearing purposes. It is also known that there are.

しかし、後者のタイプのバイブの欠点の一つは、プラスチック中に繊維が存在し ているので、そのようなプルトルージヨン及び／又はプル・ワインディングによ るプラスチック・バイブ中を通る液体が、そのプラスチック・バイブの片側から 反対側への通路を形成してしまう繊維に沿って漏れ出してしまうので、その水密 性が保証出来ない事にある。However, one of the drawbacks of the latter type of vibrator is the presence of fibers in the plastic. Because such pultrusion and/or pull winding The liquid passing through the plastic vibrator is released from one side of the plastic vibrator. Its water tightness prevents it from leaking along the fibers forming a passage to the other side. The reason is that gender cannot be guaranteed.

ＬＬ！ｌ！ｌ示 本発明の目的は、公知のプラスチック・バイブの上記の欠点を全て取り除いた複 合プラスチック・バイブであり、水密性があるのみならず、化学的に腐食性の製 品を搬送するのに適したバイブであり、しかも同時にそのような液体を高圧下で 搬送する事が出来るバイブを得る事にある。LL! l! I show The object of the invention is to provide a composite vibrator which eliminates all the above-mentioned drawbacks of known plastic vibrators. The plastic vibrator is not only watertight but also chemically corrosive. It is a vibrator suitable for transporting liquids and at the same time handling such liquids under high pressure. The goal is to obtain a vibrator that can be transported.

しかも追加的な利点としては、このようにして非常に大きな耐衝撃性を有するプ ラスチック・バイブが得られる事である。An additional advantage is that this allows for very high impact resistance. It gives you a rustic vibe.

このような目的のための上記の、さらにその他の特徴を有する本発明による複合 プラスチック・バイブは、熱可塑性合成材料による押出バイブと、それに密着す る熱可塑性又は好ましくは熱硬化性の合成材料を使ったプルトルージョン・バイ ブ又はプル・ワインディングによって得られたバイブの結合から基本的に成るも のである。A composite according to the invention having the above-mentioned and further features for such purposes Plastic Vibrator is an extruded vibrator made of thermoplastic synthetic material and a pultrusion bi-layering using thermoplastic or preferably thermosetting synthetic materials. It basically consists of a combination of vibes obtained by winding or pull-winding. It is.

一つの具体的実施例においては、これらのバイブが相互に対する回転防止の効果 を持つように、内部バイブの外面とそれに対応する外部バイブの内面とは粗な面 を持つように仕上げられ、それによって複合バイブが捻じれに対して非常に大き な抵抗を有するものである。In one specific embodiment, these vibrators have an anti-rotation effect on each other. The outer surface of the inner vibrator and the corresponding inner surface of the outer vibrator have a rough surface so that This makes the composite vibrator extremely resistant to twisting. It has a high resistance.

上記の内部バイブの外面とそれに対応する外部バイブの内面は、この目的のため に波形又はそれに類似した形に形成され、これらの各面におけるその波形、ノツ チなどが相互に連結する。The external surface of the internal vibrator described above and the corresponding internal surface of the external vibrator are for this purpose It is formed into a waveform or a shape similar to it, and the waveform and knots on each surface etc. are interconnected.

内部バイブと外部バイブの面を上述のように組み合わせることは、望ましいもの であるが、これは（本発明を）限定するものでは無く、相互に組合う二つの面を 平滑に仕上げたバイブにおいても極めて良い結果が得られるものである。Combining the aspects of internal and external vibes as described above is desirable. However, this does not limit (the present invention), and the two aspects that are combined with each other are Very good results can be obtained even with a vibrator with a smooth finish.

本発明による複合バイブは、好ましくは例えばポリプロピレン、塩化ビニール、 高密度ポリエチレン、ポリアミドなどの熱可塑性材料を押し出して内部バイブを 形成し、次にかくして形成された内部バイブの周囲に、熱可塑性若しくは、例え ばポリエステル、ビニール・エステル、エポキシなどの熱硬化性合成材料中に浸 漬した繊維または布を加熱した金型を通して引き抜くことによって、換言すれば 上記のように形成された内部バイブの周囲にプルトルージョンすることによって 外部バイブを形成して得られるものである。The composite vibrator according to the invention preferably comprises polypropylene, vinyl chloride, Extruded thermoplastic materials such as high-density polyethylene and polyamide to create internal vibes and then surrounding the thus formed internal vibrator with a thermoplastic or For example, it can be immersed in thermoset synthetic materials such as polyester, vinyl ester, or epoxy. By drawing the soaked fiber or cloth through a heated mold, in other words By pultrusion around the internal vibe formed as above This is obtained by forming an external vibrator.

明らかに１本発明による複合バイブは、またプルトルージョンにより内部バイブ を形成し、その周囲に外部バイブを押出成型して形成することも可能である。Obviously, the composite vibrator according to the present invention also has an internal vibrator by pultrusion. It is also possible to form an external vibrator by extrusion molding around the vibrator.

本発明による特徴をより良く示すために、好ましい実施例を以下いかなる意味で も本発明を限定するものでは無い例として添付した図面を参照した説明する。In order to better illustrate the features according to the invention, preferred embodiments will be described below in any sense. The invention will now be described, by way of non-limiting example, with reference to the accompanying drawings.

１乱立皿皇互１ｊ 第１図は本発明による複合プラスチック・バイブの半径方向の断面図であり、第 ２図においてはより大きな縮尺で第１図に示された部分の変形例を示し、第３図 は第２図の変形を示している。1 disordered plate royal mutual 1j FIG. 1 is a radial cross-sectional view of a composite plastic vibrator according to the present invention; Figure 2 shows a modification of the part shown in Figure 1 on a larger scale, and Figure 3 shows a modification of FIG.

発明を実施するための最良の形態 第１図において、本発明による複合プラスチック・バイブ１は１例えばポリプロ ピレン、塩化ビニール、高密度ポリエチレンなどの熱可塑性材料を押し出して得 られた内部バイブ２と、熱可塑性又は例えばポリエステル、ビニール・エステル 、エポキシなど熱硬化性材料をプルトルージョン及び／又はプル・ワインディン グによって、内部バイブ２の周囲に密着して成形した外部バイブ３によって形成 される。BEST MODE FOR CARRYING OUT THE INVENTION In FIG. 1, a composite plastic vibrator 1 according to the invention is shown, for example a polypropylene Obtained by extruding thermoplastic materials such as pyrene, vinyl chloride, and high-density polyethylene. with a thermoplastic or e.g. polyester, vinyl ester , pultrusion and/or pull-winding of thermosetting materials such as epoxies. Formed by an external vibrator 3 that is closely molded around the internal vibrator 2 by be done.

かくのごとくして得られた内部バイブは固（その中を通して化学的に腐食性の製 品を搬送することが出来、その周囲の外部バイブは極めて耐衝撃性が大きく、且 つ高圧に耐えることが出来る。The internal vibrator thus obtained is solid (through which a chemically corrosive material is inserted). The external vibrator surrounding the product is extremely impact resistant and Can withstand high pressure.

第２回においては、捻じれに対して極めて効果的な抵抗性を有するバイブを提供 するために、一方において外部バイブの内面と、他方内部バイブの外面を平滑に 又は粗な面に仕上げることが出来ることを示している。In the second edition, we will provide a vibrator with extremely effective resistance to twisting. In order to Or it shows that it can be finished to a rough surface.

そのような粗な面は例えば、内部バイブ２をバイブの長手方向に延びる波形４を 持たせて押し出し、その周囲に外部バイブ３をプルトルージョンによって形成し 、その場合バイブ３の内面が自動的にバイブ２の外面の形状に従うように形成す ることによって得られる。Such a rough surface may, for example, cause the internal vibrator 2 to have corrugations 4 extending in the longitudinal direction of the vibrator. Hold it and push it out, and form the external vibrator 3 around it by pultrusion. In that case, the inner surface of the vibrator 3 is automatically formed to follow the shape of the outer surface of the vibrator 2. It can be obtained by

バイブ２とバイブ３の間の相互結合を得るためのその他の形態、例えば長手方向 の連結を確保するような横断ノツチなどを設けることなどによっても可能である 。Other forms for obtaining mutual coupling between vibrator 2 and vibrator 3, e.g. in the longitudinal direction This is also possible by providing a transverse notch to ensure the connection of the .

第３図においては、最後に平滑な外面を有する内部バイブと平滑な内面を有する 外部バイブな結合させることも又可能であることを示している。In Figure 3, the inner vibrator has a smooth outer surface and the inner vibrator has a smooth inner surface. It shows that external vibrational coupling is also possible.

本発明が決して上述の実施例と添付した図面に示されたものに限定されるもので は無く、かかる複合プラスチック・バイブは発明の範囲から逸脱する′ことなし に例えばプラスチッり／鉄・非鉄の金属の複合材、並びにそれらの互換性の複合 材など、あらゆる種類の形態と寸法をもって実施出来るものであることは明らか である。The invention is in no way limited to the embodiments described above and shown in the attached drawings. There is no such composite plastic vibrator and such composite plastic vibrator does not depart from the scope of the invention. For example, plastic/ferrous/non-ferrous metal composites and their compatibility. It is clear that it can be implemented in all kinds of shapes and sizes, including materials. It is.
